Boxing promoter Frank Warren is planning further talks with Oleksandr Usyk's camp to try to salvage the undisputed heavyweight fight against Tyson Fury.
The bout was supposed to happen on the 29th of next month at Wembley Stadium, and Usyk had agreed to a 70/30 purse split in Fury's favour.
But the terms for an immediate rematch have proved a sticking point, with Team Usyk set to walk away.
Warren says he was hoping to rescue the fight during further talks with Usyk's promoter.
Representatives for Usyk say they have done everything within their power to make the bout happen.
Both parties still have until 1st April to agree to a deal after the WBA said it would wait until that date before ordering Usyk to fight mandatory challenger Daniel Dubois.
